The contents of transuranic elements in high-burnup spent fuel samples were determined. The activity amounts of 238Pu,
239Pu, 240Pu, 241Am, 244Cm and 242Cm were measured by alpha spectrometry using 242Pu and 243Am as tracers, respectively. A
spike addition method for 237Np was established by an alpha and gamma spectrometry using 239Np as a spike after the
optimum conditions for the measurements of 237Np and 239Np, respectively, were obtained.
A separation system using anion exchange chromatography and diethylhexylphosphoric acid extraction chromatography
was applied for the separation of these elements.
This method was applied to high-burnup spent nuclear fuel samples (40~60GWD/MTU). The contents of the transuranic
elements were compared with those by ORIGEN-2 code. Measurements and the calculations of the contents of the plutonium
isotopes 238Pu, 239Pu and 240Pu agreed to within 10% on average. The contents of 237Np agreed to within approximately 5%
except for one instance of a calculation, while those of 241Am, 244Cm and 242Cm showed higher values by approximately 19%,
35% and 14% on average, respectively, compared to the calculations according to the burnup.
